i don't buy into all this new wave weight loss stuff because most of the diet shakes are loaded with sugar and nutricianist are firmly against them for longer then say a week and say you still need to have solids with the shake drink and exercise, I was exercising about 3 times a week and other times I would walk a lot and eat less and fill up on carbs and I woud allow myself a small chocolate and I never gained weight. when the diet shakes really kicked in I was losing weight even eating mud cake now and then or jam on toast and now everyone has gone sugar concipracy like its some evil. yet my body responds well to certain sugars at breakfast and not all sugars however. I don't exercise as much now only because there is no weight loss exercise salons around here now. they all are diet shakes, gyms and diy and those diets and exercise patterns don't often work if you have long term weight issues. the shakes can give constipation and I loaded with sugar how can they be good for you? compared to say baked beans on toast or salad and tuna etc. i still like a sweet tooth now and then.
